Patented Oct. 11, 1938 UNITED STATES examiner PATENT OFFICE PRINTING MACHINE Walter T. Gollwitzer, Euclid, Ohio, assignor to Addressograph-Multig'raph Corporation, Wil-, mington, DeL, a corporation of Delaware Original application February 24, 1936, Serial No. 65,376. Divided and this application February 16, 1938, Serial No. 190,826

10 Claims.

This invention relates to printing machines of the kind through which printing devices or the like are passed to have impression operations made therefrom or to control other operations in the machine and more especially to accurately locating such devices relative to means in the machine adapted to cooperate therewith.

This application is a division of my co-pending application Serial No. 65,376, filed February 24, 1936.

Each of the printing devices that is passed through a machine of the kind to which this invention relates and from which an impression may be made may advantageously be positioned in the printing machine accurately so as to insure the accurate positioning of the impression made therefrom and thereby insure a neat and orderly appearance of the sheet receiving the impression. There are other instances where accurate positioning of a printing device or the like relative to means in the machine adapted to cooperate therewith is advantageous and hence an object of this invention is to insure accurate positioning of a printing device or the like in a printing machine or the like.

Another object of my invention is to position the printing devices fed through a printing machine accurately relative to parts of the machine operative to make impressions therefrom to insure accurate positioning on sheets or the like of the impressions made from the devices.

Another object is to enable accurate adjustment of a printing device into a predetermined position in a printing machine.

A printing device from which an impression may be made in a printing machine may also be a control device to control the making of an impression therefrom or to control an impression or other operation of other means in the machine. In my co-pending application heretofore referred to a complete machine is described wherein an impression can be made directly from a printing device bearing control means and also other impressions may be made under control of the control means on the printing device. Furthermore, if desired, such a printing and control device or merely a control device may be arranged in a machine to control the performance of mathematical or other operations and among the objects of this invention is to insure accurate positioning of such a printing and control device or control device in a machine relative to means in the machine adapted to cooperate therewith.

An example of the use to which a printing and control device may be put in a machine such as that to which I have referred is the printing of a stock dividend check including the printing of the name and address of the stockholder and the amount of the dividend to which he is entitled and which depends upon the rate of the dividend declared and the number of the shares of stock held.' Other examples are insurance company premium notices, public utility bills to customers, and the like.

A further object of my invention is to insure accurate positioning of the devices in a machine such as that to which reference has been made relative to means in the machine effecting operations therefrom or thereon and thereby insure accurate operation of such means.

A still further object is to accurately position devices introduced into a machine in control position in the machine whereby means on the device will be arranged accurately to cooperate with means in the machine so as to thereby insure accurate operation in the machine.

The selected embodiment of the invention shown in the accompanying drawings is illustrated as constructed and used in a machine adapted for the preparation of checks and more particularly dividend payment checks of a corporation, but it is to be understood that this is merely an illustrative use of the invention formany other machines adapted for other uses and other kinds of business instruments for many otherpurposes may include this invention.

The preparation of dividend checks of a large corporation has been an arduous and time-conthe preparation of dividend checks has been simplified and speeded up has been by providing the names or other identification of the shareholders of a corporation on printing devices which have been passed through a printing machine to address or otherwise identify the checks and, while printing of such checks by use of such devices facilitated the preparation and distribution thereof, it was still necessary to perform other operations on the checks as, for example, entering the amount thereon. Other operations have been necessary to properly prepare the checks for dis tribution and, while printing addresses or other identification on the checks by use of printing devices facilitated preparation thereof, it did not solve all the problems entailed in economically preparing checks.

The preparation of dividend checks has been facilitated by not only providing devices for printing the name and address or other identification of a shareholder but which also carry control means so that the entire record may be printed by the devices. Such a device is illustrated and described in my co-pending application Serial No. 65,377, filed February 24, 1936. The record, by way of example, may be the identification of a shareholder and the amount which the shareholder is to receive by reason of the declaration of a dividend. This amount represents the number of shares owned by a shareholder multiplied by the rate of the dividend. Such a record may be provided on the printing device in a variety of ways of which the now to be described manner is but illustrative.

For the purpose of illustrating this invention I have shown a printing and control device of the kind disclosed in my aforementioned copending application Serial No. 65,377. Such a device includes a carrier or a frame, a removable plate, an index card and a control card. It is to be understood, however, that the invention is not limited to the use of such structure of printing and control devices but could, if desired, be used with printing devices or printing and control de-- vices of any approved structure.

I have shown a printing and control device D, Fig. 3, including a frame 40 on which a flat metal plate 4| is removably retained preferably adjacent the lower part thereof. This plate is adapted to be embossed or otherwise provided with printing characters from which the name and address or other identification of the shareholder of a corporation may be printed. In addition to this the printing device is also provided with an index card 42 bearing an impression from the printing characters on the plate 4| which facilitates filing and other handling of the device. The index card is preferably located in one upper corner of the frame 40.

I provide a plurality of openings 43 preferably in the other upper corner of the frame. For the purpose of illustration I have provided nine rows of openings with five openings in each row in transverse and longitudinal alignment with each other. Each row may be used to indicate the digit of a number or other numerical accounting data or the like and I may therefore arrange the indications of a nine place number on the printing device and, when expressed in terms of dollars and cents, I may indicate any amount up to 9,999,999 dollars and 99 cents. I also provide but five openings in each row and I utilize these openings in accordance with a system or code whereby I am enabled to provide an indication for any digit in every row. Such systern or code is more fully explained in my aforementioned co-pending application Serial No. 65,376.

In order to render operative only selected of the openings 43 I employ a control card 44 which is disposed over the openings, and by forming openings in this control card in alignment with selected of the openings 43 in selected of the rows thereof comprising five openings I provide aligned openings in predetermined positions and thereby afford control means which in the present instance indicate the digits from 1 to 9 in the various rows. The control card 44, plate 4| and index card 42 are removably secured on the frame by suitable retaining devices.

While this invention is primarily directed to making. impressions directly from and under control of the printing devices, this term being used hereinafter as generic to printing devices per se and also printing and control devices of various structures, I have shown a machine which will completely print a dividend check and to this end I have provided a printing couple wherein the date, the number and the signature may be conveniently printed, a variable printer under control of the printing device for printing the form other mathematical operations, and it is likewise advantageous to prepare a record of the amounts printed, and the machine I have selected for illustration includes a calculating machine, and more particularly an adding ma chine, wherein a total of the amounts printed on the various checks may -be accumulated and wherein a record of the amounts so printed may be prepared.

A roll of paper R, Figs. 1 and 2, is mounted in a suitable supporting stand and a web W is withdrawn from the roll and passed between the cylinders of a suitable printing couple 5| wherein the signature, date and number, comprising the reoccurring but changeable data, is printed.

In the form of the invention illustrated I employ a web of a width equal to the desired length of the checks for checks are usually of greater length than width and by severing the checks from the web in this manner I am enabled to sever a great many more checks from a web of given length than I would be able to do if the web were the same width as that desired of the checks and the web was severed transversely of the checks rather than longitudinally thereof. The leading edge of the web is therefore fed past a severing device I40 in an amount equal to the desired width of the check. The severing device then operates as disclosed in my co-pending application Serial No. 65,376 to sever the check from the web.

The checks or sheets S severed from the web are deposited on a pan from which they are fed transversely of the machine to receive impressions under control of the printing and control devices and directly from the devices and then into a printing couple 2' wherein the form, such as the name of the payee corporation and the name of the bank on whom the check is drawn, is

101. PRINTING.

printed. From the printing couple the sheets are fed to a suitable collecting tray H.

During-ethe transverse movement of the sheet across the machine they travel in a guideway G which is provided with two strips 203 and 204 undercut on their adjacent sides and the sheets S pass through these undercut sections.

The addressing machine includes a frame 225, Figs. 1 and 2, in which a main drive shaft 226 is journaled. Power is supplied to this main drive shaft from a. suitable source. A cam shaft 221 is -aiso journaled in the frame 225 and in the present instance a suitable gear train interconnects the main drive shaft 226 and the cam shaft 221 for operation in a one-to-one ratio so that the cam shaft will make one revolution each time the drive shaft makes one revolution. A rod 229 is mounted in the frame 225 adjacent the cam shaft 221. The means which control the movement of the sheets through the sheet guideway G are mounted on the rod 229 and are operated by cams carried by the cam shaft 221. Stop fingers are provided in the present instance which are movable to and from engagement with theieading edgfofsheets moving througfthe guidway, these fingers being movedzinto stopping position and holding the sheets against further movement until a predetermined time in the operation when they are retracted from engagement with the sheets to permit the sheets to move to the left, as viewed in Fig. 1, through the guideway.

The platen P makes impressions on the sheets S from printing devices D through an ink ribbon IR although it is to be understood that impressions could be made from printing devices in any desired way depending, of course, upon the nature of the printing devices, the ink ribbon IR being a convenient way to make impressions when the printing characters are embossed on the plate such as 4! as in the present instance.

Printing devices are initially introduced into the machine by stacking them in a magazine M at the rear end of the printing device guideway 243. Chains, such as 244, are mounted at each side of the printing device guideway and are directed about sprockets 245 and 246 respectively mounted on shafts 241 and 246 mounted in the frame 225 beyond the front and rear ends of the printing device guideway 243. Pawls such as 249 are provided at spaced intervals on the chains 244 and these pawls successively move into position to engage the lowermost printing device in the magazine M and then, as a step-by-step movement is imparted to the chains, the printing devices are successively moved through stations until they reach printing position below the platen P after which they are discharged past the guide 250 to be collected in the usual manner. In the present instance the printing devices move through three stations intermediate the magazine M and printing position.

A step-by-step movement is imparted to the chains 244 from a rocker 25! carrying a pawl 252 successively engageable with spaced pins 253 mounted in the sprocket 245. The rocker 25! is mounted on a shaft 254 journaled in the frame 225. An arm 255 is fast on the shaft 254 and as the shaft 226 rotates the arm 255 and rocker 25! are rocked to successively disengage the pawl 252 from one of the pins 253 and engage it with the succeeding pin and to then impart an advancing movement to the chains 244 as the newly engaged pin 253 is driven forwardly.

' The platen P is carried by a platen arm 26! Examiner pivotally mounted as at 262 on the frame 225.

The platen arm carries a pair of rollers 263 and another pair of rollers 264 which respectively? engage pairs of conjugated cams 265 and 266 that are releasably connected to the shaft 226. When the conjugated cams 265 and 266 are connected to the shaft 226 they operate in timed relation with the movement of the chains 244, and these cams cooperate with the rollers 263 and 264 on the platen arm 26! to move the platen on said arm downwardly to make an impression from the printing device during an at rest interval in the step-by-step movement of the printing devices through their guideway and to elevate the platen out of engagement with the printing devices at a time when a feeding movement is imparted to the printing devices. It, of course, is to be understood that if desired the feed of the printing devices can be so controlled that more than one impression can be made therefrom prior to their discharge from printing position. Also an impression operation of the platen? may be arrested in event no sheet is. fed into printing position and therefore operation of the platen P is also under control of the sheets fed through the machine, arrangements: for these purposes being well understood in the art.

The variable printer illustrated in this application is preferably associated with a calculating machine which, in the present instance is an adding machine, so that the amounts printed on the checks may be totalized to facilitate verification, and'preferably the amounts printed on the business instruments by the variable printer are also printed on the detail strip passing from the roll 444 in the calculating machine to afford a record useful for verifying purposes and the like.

The set-up of the variable printer is under control of the printing devices moving through the printing device guideway 243 and a detector 525, Figs. 2, 4 and 5, is associated with the print ing device guideway in a position to cooperate with the printing device in a station two removed from printing position below the platen P. The detector 525 is positioned to cooperate with the openings 43 and the control card 44 in the printing device as they move through the printing device guideway. The detector 525 is carried by a bracket 526 pivotally mounted in the frame of the printing machine as indicated at 521. A lug 526 is provided on the upper side of the detector 525 and the lower end of a link 529 is pivotally connected thereto. A rocker 536, Fig. 2, is pivotally mounted on a rod 53! mounted in the frame of the printing machine and the rocker 535 includes an arm to which the upper end of the link 529 is connected. An arm 533 is also provided on the rocker 530 and carries a roller 534 that follows the cam 535 fast on the shaft 226. The cam 535 imparts a rocking movement to the rocker 536 to thereby lower and raise the link 529 to correspondingly raise and lower the detector 525 and inasmuch as such movement is effected from the shaft 226 it occurs in timed relation with the operation of the platen P and the movement of the printing devices D through the printing device guideway 243, and the detector 525 is moved into cooperating relation with the printing device D therebelow during an at rest interval in the step-by-step movement of the printing devices through the printing device guideway.

A plurality of detector pins 536 are mounted in the housing 531 of the detector 525. The housing 531 is preferably made of insulating material and the detector pins 536 are reciprocally mounted in pockets 538 formed in this housing. The pins are urged downwardly by springs 539. Nine rows of detector pins are provided transversely across the detector 525 and five pins are provided in each of these rows, and it will thus be seen that there is a detector pin 536 for each opening 43 in the frame 40 of the printing device D. A metallic plate 540 is mounted in the housing 531 and an electrical conductor 54| is connected thereto. Openings 542 are provided in the plate 548 in alignment with the first four pins 536 in each of the nine rows of openings and plungers 543 provided on these pins 536 slide in the openings 542. A metallic bar 544 is mounted in the housing 531 and is insulated from the plate 540 by an insulating strip 545 and has an electrical conductor 546 connected thereto. Openings 541 are provided in the bar 544 in alignment with the last pin in each of the nine rows of openings and plungers 548 on these pins slide in these openings. It will thus be seen that the first four pins in each of the nine rows of openings may be connected in an electrical circuit of which the conductor 54! is a part, while the last pin in each of the nine rows of openings may be connected in another electrical circuit of which the conductor 546 is a part.

In the printing device guideway below the detector 525 at what may be called detecting position, a block 549 of insulating material is provided. A plurality of contacts 550 are mounted in this block 549 in alignment with the detector pins 536, which is to say, in alignment with the openings 43 in the printing device D in detector position, and if no printing device were interposed between the detector pins 536 and the contacts 550 and the detector 525 was moved toward the printing device guideway each pin 536 would engage a contact 550.

It has been explained heretofore that the control cards on each of the printing devices D have perforations therein in alignment with selected of the openings 43 to thereby indicate digits from 1 to 9 in the various rows of openings. Hence, when the control card is in detector position and the pins 536 are lowered only those pins 536 aligned with the openings in the control card will pass through the card to establish an electric circuit which is indicative of particular digits. The circuit is connected to the calculating mechanism through conductors as 516 to reproduce the digits indicated by the openings in the control card.

All the printing devices in a sequence passed through the printing machine are not always used in such a manner that impressions are made directly therefrom and under control thereof and this is determined by employing identification means on the printing devices. The identification means may be removable tabs T which may be connected to the frames 40 of the printing devices in any suitable manner, or other suitable identifying means may be provided. Tabs such as the tab T may be secured to the printing device in any one of a plurality of positions. In the present instance when an impression is to be made from a printing device D, a tab T is removably fast in the printing device in the first of the tab receiving positions and suitable means in the machine cooperate with this tab T to arrange the machine so that impressions will be made directly from the printing device and also under control thereof. However. when a tab is not provided in this position impressions are not made directly from and under control of the printing device.

In order to determine whether or not an impression is to be made from the printing device a detector bar 511, Figs. 4 and 5, is provided. The detector bar 511 is carried by arms 518 pivotally mounted, as indicated at 519, on the side members of the frame 526. Pins 586 and SH are provided at opposite ends of the bar 511 and rest against the upper edges of the side frame members to limit downward movement of the detector bar 511 and also for the purpose of operating switches in a manner to be described presently. A plurality of openings 582 are provided in the bar 511 and a feeler pin, such as 583, is selectively mounted in these openings 582 to engage a tab such as the tab T in the various possible positions of the tabs on the printing devices D. In the present instance where impressions are to be made directly from and under control of the printing devices when a tab T is located in the first position on a printing device the pin 583 is located in the first of the holes 582 Thus since the bar 511 rests on the frame 526, when said."

frame is lowered with the detector 525, the pin' 583 engages a tab T when one is one the printing device D in detector position. The engagement of the pin 583 with such a tab T arrests downward movement of the bar 511 and when movement of the bar 511 is so arrested switches controlled by the pins 580 and 58| are closed.

The switches controlled by the pins 580 and 58l are best illustrated in Figs. 4 and 5. In Fig. 5 a block 584 of insulating material is fast on one of the side frame members of the frame 526. Blades 585, 586, 581 and 588 are mounted in the block 584 one above the other. The blade 585 carries a contact 589 adapted to cooperate with a contact 596 on the blade 586. The blade 581 carries a contact 5! adapted-to cooperate with a contact 592 on the blade 588. A block of insulating material 594 is provided on blade 581 and when blade 586 is moved upwardly the contacts 59l and 592 are engaged. The blade 585 is provided with an extension 593 which overlies the pin 580 so that when the downward move-. ment of the pin 580 is arrested the contacts 589 and 596 will engage.

A conductor 595, Fig. 5, is provided and a conductor 596 leads from the conductor 595 to the blade 581, and a conductor 591 leads from the conduotcr 595 to the blade 585. The conductor 546 connects the blade 586 with the conductor bar 544. The conductor 54! connects the blade 588 with the contact plate 540. Thus when the contacts 589 and 598 are engaged circuit is established between the blades 585 and 586 prior to the time the contacts 59l and 592 establish circuit between the blades 581 and 588 and therefore current is supplied to the bar 544 prior to the time it is supplied to the plate 540.

From the machine thus far described it can be readily appreciated that it is highly desirable if not essential that the printing device be very accurately located in the printing or control position in order for the parts of the machine to cooperate with means on the printing device in the manner intended. Therefore I have provided by this invention suitable means to insure accurate location of the printing device,

When the printing devices move through the printing device guideway and into position below the detector 525 it is necessary that the devices be positioned accurately so as to prevent grounding of the pin 536 on the metallic frames of the printing devices. Furthermore, it is essential that the pins 536 move through proper openings in the card, so as to prevent the entry of something other than the indicated digit. This is accomplished by accurately positioning the printing device relative to the detector 525. To this end each printing device has a notch 150 in one edge thereof and this notch is located accurately relative to the openings 43 in the printing device. Therefore, if means in the machine are accurately located relative to the detector 525 and this means is engaged in the notch 150, the printing device will be accurately located relative to the detector.

Means suitable for this purpose are illustrated in Figs. 4, 7 and 8 wherein a leaf spring 15l is fast to the side of the printing device guldeway. A block 152 is fast on the leaf spring 'l5l and in the present instance this block is V-shaped to correspond to the V-shaped notch 150 in the printing device. If, however, the notch in the printing device is of some other shape, this block will be of a corresponding shape.

In order that the printing device will be located relative to the detector 525 immediately prior to the cooperation of the detector with the printing device the block 152 is engaged in the notch just prior to the time the pins 536 approach the printing device in detecting position.

Such movement of the block I52 ls accomplished in the present instance by providing a cam I53 on the leaf spring 'l5l and a conical headed adjustable pin 154 in the frame 526. Then when the frame 526 moves downwardly the pin 754 engages the cam I53 and forces the block 152 through the opening 155 in the side of the printing device guideway, and the block thereupon seats in the notch 150 to position the printing device relative to the detector. In event the printing device need be shifted I provide rollers 156 on the opposite side of the printing with these rollers any necessary shifting of the printing device is facilitated.

From the parts just described it is evident that I have provided means whereby the printing device will be accurately located or adjusted after being deposited in printing position by the printing device feed mechanism. I have also illustrated and. described the locating and adjusting means as being embodied in a specific type of printing machine. However, it is to be understood that the locating and adjusting mechanism may be embodied in printing machines of many other types than that herein described and illustrated.

I have explained the printing of a check and more particularly a check for the purpose of paying dividends, but it is to be understood that checks for any purpose, or other business instruments such as, for example, notices, bills and the like, may be prepared in a machine embodying the invention without departing from the scope thereof.

I have illustrated and described the preferred form of my invention, but it is to be understood that I do not wish to be limited to the precise details set forth but desire to avail myself of such changes and alterations as may be desired to enable it to be used for the purpose for which it is or may be adapted.
